Didn't fully understand the "logic" between ROMSET versions

you can delete roms within emulationstation. it's the 'delete' in the 'edit metadata' options menu of each rom.

@dazza Well, there you go--maybe not bound to a key, but it's in there.

lr-imame4all is libretro/retroarch, so does support savestates.

I know it's off topic but a quick question. If it's to far off topic I can open a new post or problem ticket if that helps as it mostly relates to lr-mame2003 with a quick question on lr-imame4all.

I was doing some testing over the weekend and I noticed when I try to do a save state in lr-imame4all I get a message in the lower left stating save states aren't supported in this core or something to that effect. I can change slots but I can't save. I am running an older version of RetroPie 3.7 are save states for lr-imame4all recent?

Also is 4 players supported in lr-mame2003? I was able to use the Config Menu (Tab) to configure 4 joysticks under General (Input). All four sticks allowed input but once I started a game (Gauntlet) I could only get 1 player working. I have the update you walked me through on another thread that allows the history.dat to work properly. I am not sure on how to locate the build version though of lr-mame2003.

The other minor thing I noticed in lr-mame2003 is several management keys that just don't work like F4 (FPS) and DOUBLEQUOTE (On-screen Display), etc.

I've been testing things out in hopes to get fully on lr-mame2003 and the few games left in AdvMAME.

whoops, sorry! i assumed all RA cores would support save states, but apparently not! i've not tested lr-imame4all , but if you get that message i would suggest maybe logging an issue here: https://github.com/libretro/mame2000-libretro/issues - they definitely work in lr-mame2003 so i would hope it shouldn't be too difficult to implement.

Also is 4 players supported in lr-mame2003? I was able to use the Config Menu (Tab) to configure 4 joysticks under General (Input). All four sticks allowed input but once I started a game (Gauntlet) I could only get 1 player working.

whilst i can get 2 players working, i can't seem to get 3 or more. with either gauntlet or xmen 4 player (didn't try others). hmm, there's definitely a problem here! thanks for alerting me to it. i will look into this now - 4+ players is crucial!

The other minor thing I noticed in lr-mame2003 is several management keys that just don't work like F4 (FPS) and DOUBLEQUOTE (On-screen Display), etc.

FPS is supported in retroarch (select + retropadX to get to the RGUI, and then it's in video options), so that wouldn't need implementing. not sure what the on-screen display normally does in these older versions of MAME?

Ok, I opened a ticket for save states.

I will check Retroarch for FPS. That's more like a handy feature than a needed one to see how a game performs.

Yes 4 player is a must! I grabbed all the 4 players games I could find. Even a bad one is fun sometimes with the right group of people! :)

The on-screen display is for overclock, volume, brighness, gamma, etc. Here's the list on cycle through for mame4all. Most of the options can be adjusted in other places I believe.

Volume 0db
YM-2151 #0 Ch1 (Lt) Volume 75%
YM-2151 #0 Ch1 (Rt) Volume 75%
uPD7759 #0 Volume 30%
uPD7759 #1 Volume 30%
Overclock CPU0 100%
Overclock CPU1 100%
Brightness 100%
Gamma 1.00

Toggles the On Screen Display. When the on-screen display is
visible, you can use the following keys to control it:

Up - select previous parameter to modify
Down - select next parameter to modify
Left - decrease the value of the selected parameter
Right - increase the value of the selected parameter
Enter - reset parameter value to its default
Control+Left - decrease the value by 10x
Shift+Left - decrease the value by 0.1x
Alt+Left - decrease the value by the smallest amount
Control+Right - increase the value by 10x
Shift+Right - increase the value by 0.1x
Alt+Right - increase the value by the smallest amount

If you are running with -debug, this key sends a ‘break’ in emulation.

4 player for sure works in the current mame2003 binaries, but I do have an issue with my latest changes (which weren't accepted yet anyway!). either way, I fixed the problem in my changes and will resubmit the PR for review soon.

caver01

@dankcushions Cool! I have been running fine with 4-players but have not updated 2003 in a while. I am really looking forward to testing the trackball/spinner games. That will bring over another batch of games from AdvanceMAME to lr-mame2003.

Hello forum people!
I was just Googling about rollbacks and romsets and stumbled upon this thread. Read it almost completely until I got too baffled to continue (hint: I'm a n00b).
Anyway, I thought this was the perfect place to post my problem and ask for some assistance...

I need the 0.134u4 romset. How exactly can i get it using the current rom set?

If I understood correctly from reading this page, I would need:

the latest romset
the corresponding rollback set (i.e. the same version as the latest romset, right?)
the 0.134u4 .dat file
clrmamepro

Am I right? Or do I need anything else?

Also, would I need any CHD files? I know these are reserved for more recent, bigger games, and given the overwhelming size of these, I may end discarding these games. My question is, if I "need" the CHD files to make a proper rollback conversion.

my first question would be: why do you want the 0.134u4 romset? none of the retropie emulators use that set.

you need CHD files if you want to play the games they are for.

nunofrsc

@dankcushions Because that's the latest version of SDL MAME Wii, which is where I will be playing games.
So I don't need the CHD files for a proper conversion - only if I intend to play the games which require it, right?
